Hnub Ci Inverter Nrog Dc rau Ac 24v

GI series hnub ci inverter nrog DC rau AC 24v

Cov txheej txheem ua haujlwm ntawm Circuit Court:

a>Tom qab qhov hloov S tau qhib, qhov hluav taws xob hla lub transformer winding N1 yog nce zoo thiab qis qis, thiab qhov hluav taws xob hla N2 winding txuas rau nws kuj nce zoo thiab qis qis. Yog li ntawd, VD1 nyob rau hauv lub xeev, VD2 yog nyob rau hauv lub off state, thiab tam sim no ntawm inductor L nce maj mam;

b>Tom qab S raug tua, lub inductor L freewheels los ntawm VD2, thiab VD1 raug tua. Tom qab S raug muab tua, qhov excitation tam sim no ntawm transformer ntws rov qab mus rau lub hwj chim mov los ntawm N3 winding thiab VD3, yog li S raug rau voltage tom qab nws muab tua.

c>Cov tub ntxhais hlau nplaum ntawm lub transformer yog rov pib dua: Tom qab qhov hloov S tau qhib, qhov kev tawm dag zog tam sim no ntawm lub transformer pib ntawm xoom, thiab nce linearly nrog lub sij hawm nce mus txog rau thaum S raug tua. Txhawm rau tiv thaiv qhov saturation ntawm magnetizing inductance ntawm lub transformer, nws yog ib qho tsim nyog yuav tsum tau sim ua kom cov hlau nplaum tam sim no poob rov qab mus rau xoom nyob rau hauv ib lub sij hawm ntawm lub sij hawm tom qab S raug muab tua mus rau lub sij hawm tom ntej nws tig rov qab. Cov txheej txheem no yog hu ua lub core reset ntawm lub transformer.

Qhov zoo tshaj plaws waveform ntawm lub voj voog rau pem hauv ntej: Lub sijhawm pib dua ntawm lub tshuab hloov pauv yog: Tist=N3 *Ton / N1 Cov zis hluav taws xob: Thaum cov zis lim inductor tam sim no txuas ntxiv: Uo / Ui=N2 * Ton/N1*T
